CORNER OR FASTENING FOR SHOW-CASES.

SPECIFICATION forming part Of Letters Patent No. 722,588, dated. March10, 1903.

Application filed August 23,1902. Serial 110 120,831. (No model.)

To all whom it may concern.-

Be it known that I, OTTO C. KADE, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois,have

invented new and useful Improvements in molding, as well as frames forholding glass plates at points intermediate of their edges, maybeentirely dispensed with, and thus permit the production of an attractiveshow-case of a strong and durable nature with a minimum cost in themanufacture of the same.

The invention consists in" the construction and arrangement of theseveral parts, which will be more fully hereinafter described andclaimed.

In the drawings, Figure 1 is a perspective view of a portion of ashow-case composed of glass plates and illustrating one of the improvedcorners applied thereto. Fig. 2 is a section through the corner of aportion of the show-case shown by Fig. 1 and the improved device takenin a diagonal plane. Fig. 3 is a detail perspective view of the improvedcorner or fastening, showing the parts thereof separated. v

Similar numerals of reference are employed to indicate correspondingparts in the several views.

The numerals 1 and 2 designate side and end plates, and 3 a top plate,of a show-case, said plates being of glass and having the exposed edgessuitably finished. To protect the side and end plates, the edge portionof the top plate, at the sides and ends thereof, extends over themembers of the show-case below, and thereby also forms an ornamentalcase. The improved corner or fastening consists of a stifi-metalcorner-socket at, shaped to embrace a portion of the side,-end, and topplates 1, 2, and 3 and also having a hollow head 5 to compensate for theedge extension of the top plate 3. The corner or fastening 4 is ofapproximately'triangular form, and extending downwardly and inwardly atan angle of inclination from the upper angle 6 of the improved device isa bolt-rod 7, which is passed through suitable small openings 8, formedin the adjacent portions of the plates 1, 2, and 3. A triangularclamping-block 9 is fitted over the inner end of the bolt-rod 7, saidblock having an outwardly-flared socket 10 to permit it to be appliedover the said bolt-rod and remain in loose connection with said roduntil a clamping-nut 11 is applied to the inner screw-threaded extremityof the bolt-rod and brought firmly to bear against the inner face of theblock 9. When the nut 11 is applied and contacts with the block 9, thelater is drawn upwardly into place and firmly bears at its three sides,respectively, against the side, end, and top plates 1, 2, and 3 and islocated far enough away from the intersecting terminations of saidplates at the angle thereof forming the corner to prevent fracture ofthe plates. When the nut 11 is turned against the block 9 and the lattercaused to closely bear against the inner side of the plates-adjacent totheir angle of intersection, the improved corner or fastening 4 istightly drawn against the outer portions of the said plates, as clearlyindicated by Figs. 1 and 2. Owing to the approximately triangular formof the socket or fastening 4, the plates 1, 2, and 3, adjacent to theirangles of intersection, are immovably held, and the side and top membersof the socket 4 closely bear against said plates, and'the hollow beadsnugly receives the extended edge portions of the top plate 3. By thismeans all the parts of the improved corner-fastening are reliably andimmovably held in engagement with the corner of the case, and after allthe corners are applied to a case the latter is held rigid with astrength equal to that of cases employing frames or moldings to receivethe edges of the glass plates.-

The improved device is also very convenient in view of the rapidity withwhich it can be applied or detached in setting up or tak-.

ing down show-oases, and as it does not require the knowledge of askilled person to apply the corner the show-case composed of glassplates without side and end frames or moldings can be reduced and packedclosely during transportation or storage and afterward easily set up inoperative position.

It is proposed to make all the parts of the improved corner or fasteningof metal and suitably ornament the same, particularly the socket 4, andfor the purpose of practically applying the clamping-block 9 to theplates the side edges thereof are beveled or cut at an angle ofinclination, as clearly shown by Fig. 3. As a further means offacilitating the application of the clamping-block 9 the inner portionsof the corners are cut away to form curved bevels, as at 12, and in viewof the formation of the socket 10, which is located in the center of theblock 9, the latter will automatically adjust themselves to the innerfaces of the plates 1, 2, and 3 when applied.

To accommodate the application of the improved corner or fastening tocases of various sizes, changes in the proportions, dimensions, andminor details of construction may be resorted to without in the leastdeparting from the principle of the invention.

Having thus fully described the invention, what is claimed as new is 1.A corner or fastening of the class set forth comprising an approximatelytriangular socket having depending sides and a top member and alsoprovided with a bolt-rod extending from the upper angle thereof at adownward inclination, a triangular-shaped clamping-block to loosely fitover the said bolt-rod, and a clamping-nut removably engaging the saidrod.

2. A corner or fastening of the class set forth comprising a socket tofit over the exterior of the corner of a case or the like and providedwith an inwardly-extending and downwardly-inclined bolt-rod, and meansfor engaging the said bolt-rod within the plane of the socket to firmlyhold the latter in applied position.

3. A corner or fastening of the class set forth, com prising asocketmember of approximately triangular form and having an upper surroundinghollow bead, and means for securing the said socket in applied position.

In testimony whereof I affix my signature in presence of two witnesses.

OTTO C. KADE.
